Chegg Tutors was founded in 2011 as InstaEDU and launched into public beta in May 2012. At that time, the company also announced that it had raised $1.1M in venture capital funding from The Social+Capital Partnership. [2] Two of the company's co-founders had previously run an in-home tutoring company called Cardinal Scholars.
Chegg stock was a pandemic darling stock of sorts as education moved online and the company thrived, sending the stock to an all-time high of $113 per share in early 2021.
Purdue University prohibits students soliciting answers using Chegg's homework help: "While Chegg can be helpful to access textbooks and more practice problems, using this resource to find assignment answers is considered academic dishonesty because it is a form of copying and plagiarism.". [55]
The Jacobian at a point gives the best linear approximation of the distorted parallelogram near that point (right, in translucent white), and the Jacobian determinant gives the ratio of the area of the approximating parallelogram to that of the original square. If m = n, then f is a function from R n to itself and the Jacobian matrix is a ...
In numerical analysis, multivariate interpolation or multidimensional interpolation is interpolation on multivariate functions, having more than one variable or defined over a multi-dimensional domain. [1] A common special case is bivariate interpolation or two-dimensional interpolation, based on two variables or two dimensions.
Supplemental instruction (SI) is an academic support model that uses peer learning to improve university student retention and student success in high-attrition courses. [1] [2] Supplemental Instruction is used worldwide by institutions of higher learning.
In geometry, a point is an abstract idealization of an exact position, without size, in physical space, [1] or its generalization to other kinds of mathematical spaces.As zero-dimensional objects, points are usually taken to be the fundamental indivisible elements comprising the space, of which one-dimensional curves, two-dimensional surfaces, and higher-dimensional objects consist.
In mathematics, a parametric equation expresses several quantities, such as the coordinates of a point, as functions of one or several variables called parameters. [ 1 ] In the case of a single parameter, parametric equations are commonly used to express the trajectory of a moving point, in which case, the parameter is often, but not ...
